IPC: F16H55/26
Filed: 2006-10-04
Abstract: <P>PROBLEM TO BE SOLVED: To prevent fatigue rupture by enhancing the deddendum strength of a rack tooth of a rack shaft.  <P>SOLUTION: A line A is a reference line coincident with a pitch line of a reference rack tooth 2 at a central portion of the rack tooth. The pitch line of the rack tooth 2a at right and left ends of the rack shaft 1 is positioned at the tip side (upper side in Fig.1) of the rack tooth of the reference line A. Namely, the tooth height of the rack tooth 2a of each right and left end of the rack shaft 1 is higher than the tooth height of the rack tooth 2 at the central portion in tooth shape structure. By this constitution, the tooth heights of the rack teeth 2a, 2a at the right and left ends of the rack shaft 1 become higher than the tooth height of the reference rack tooth 2, and tooth thicknesses 3a, 3a of the rack teeth 2a, 2a positioned at the right and left ends becomes thicker than the tooth thickness 3 of the reference rack tooth 2. The deddendum strength is enhanced and an effect for preventing the fatigue rupture can be obtained.  <P>COPYRIGHT: (C)2008,JPO&INPIT
